Description

Technical Field

[0001] This utility model relates to the field of building installation engineering technology, and in particular to a combined cable tray elbow. Background Technology

[0002] Cable tray elbows are a key component of cable tray systems. They are primarily used to address situations where cable routing needs to be altered. Installed at the corners of cable trays, they can change the cable's path. Cable tray elbows are necessary when cable routing needs to be adjusted according to the spatial structure, such as at building corners, between floors, in machine room corners, or when encountering walls, pipes, or other equipment.

[0003] Patent application number 202120628165.9 discloses a cable tray bend, including a cable tray bend with a first bridge frame at one end, and the cable tray bend includes a base plate, with a first side plate and a second side plate bent on the side of the base plate, a third side plate and a fourth side plate bent at both ends of the second side plate, a first folded edge bent at the top of the first side plate, a second folded edge bent at the top of the second side plate, and a fifth side plate bent on both sides of the first bridge frame, with a third folded edge and a fourth folded edge bent at the top of the fifth side plate.

[0004] However, the connection method of traditional combined cable tray elbows may not be strong enough. During installation, if the size or angle of the elbow does not match the actual situation, secondary processing or adjustment is required. If external pressure is applied, the elbow may deform or break, which may cause the cable to loosen or fall off, affecting the stability and safety of the cable tray system. For example, due to the loose connection, the connection between the cable tray and the elbow or between elbows may become loose, resulting in the elbow's weak ability to withstand external pressure. When the elbow is subjected to external force, it may deform, causing the cable to be squeezed or stretched, and thus loosen or fall off. Utility Model Content

[0005] This utility model discloses a combined cable tray elbow, which aims to solve the technical problems that the connection method of traditional combined cable tray elbows may not be strong enough. During the installation process, if the size or angle of the elbow does not match the actual situation, secondary processing or adjustment is required. If external pressure is applied, the elbow may deform or break, which may lead to the cable loosening or falling off, affecting the stability and safety of the cable tray system.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A combined cable tray elbow includes a first cable tray and a second cable tray, the first cable tray and the second cable tray being connected by a hinge, and further includes:

[0008] Adjustment mechanism: Located between the first bridge frame and the second bridge frame, the adjustment mechanism includes a bridge frame elbow, which includes a first folding plate, a second folding plate, and a third folding plate. The first folding plate is fixedly connected to one side of the first bridge frame. The top outer walls of the first folding plate and the second folding plate are respectively provided with a second limiting groove and a first limiting groove. The top inner walls of the second folding plate and the third folding plate are respectively fixedly connected with a first limiting post and a second limiting post. The first limiting post and the second limiting post are respectively slidably connected to the inner walls of the second limiting groove and the first limiting groove. Limiting mechanism: Located on the top outer wall of the first bridge frame.

[0009] By adopting the above technical solution, the angle of the cable tray bend can be flexibly adjusted within a certain range, avoiding deformation or breakage at the bend, which could lead to cable loosening or detachment. This improves the stability and safety of the cable tray system. Specifically, during installation, the positions and angles of the first and second cable trays are first determined. When the angle of the cable tray bend needs to be adjusted, the third folding plate can be pushed, causing the second and first limiting posts to slide within the first and second limiting grooves, respectively. This changes the folding angle positions of the third and second folding plates. This design allows the cable tray bend to be adjusted within a certain range while maintaining the stability and integrity of the structure. One end of the first, second, and third folding plates is connected to the outer circumference of the support column via bearings. This connection method allows the cable tray bend to rotate and adjust smoothly on the support column, thus meeting the cable layout requirements at different angles. After the cable tray bend is adjusted to the required angle, the position of the cable tray bend is fixed using a limiting mechanism to ensure its stability and safety, matching it with the cable layout and preventing accidental movement or deformation during installation or use.

[0010] In a preferred embodiment, the top outer wall of the first bridge frame is provided with a connecting assembly, the connecting assembly including two fixing blocks, one of the fixing blocks being installed on the top outer wall of the first bridge frame, and a support column being provided between the two fixing blocks. One end of the first folding plate, the second folding plate, and the third folding plate are all connected to the circumferential outer wall of the support column via bearings, and a stop block is provided on the bottom outer wall of one of the fixing blocks.

[0011] In this design, one end of the first, second, and third folding plates is connected to the outer circumference of the support column via bearings. This allows the cable tray elbow to rotate and adjust smoothly on the support column, thus meeting the cable layout requirements at different angles. The use of bearings also reduces friction and wear, extending the service life of the cable tray elbow. The main function of the stop block is to limit the rotation range of the cable tray elbow. When the cable tray elbow is adjusted to the required angle, the stop block will prevent it from rotating further, thereby ensuring the stability and safety of the cable tray elbow.

[0012] In a preferred embodiment, the limiting mechanism includes a toothed ring connected to the top outer wall of one of the fixed blocks via a bearing. The top outer wall of the third folding plate is provided with a toothed plate that meshes with the toothed ring. The top outer wall of one of the fixed blocks is provided with a connecting post. One end of the connecting post is fixedly connected to a mounting plate. A connecting rod is fixedly connected to the circumferential outer wall of the connecting post. A return spring is wound around the circumferential outer wall of the connecting rod. One end of the return spring is provided with a limiting block. The top outer wall of the toothed ring is provided with a connecting ring. The circumferential inner wall of the connecting ring is provided with a plurality of equally spaced third limiting grooves and connecting grooves. The depth of the connecting grooves is less than the depth of the third limiting grooves.

[0013] In this solution, when it is necessary to adjust the angle of the cable tray elbow, first manually compress and move the return spring and the limiting block towards the support column, and then manually rotate the third folding plate to drive the toothed plate to move relative to the toothed ring. Since the teeth of the toothed plate and the toothed ring mesh with each other, the rotation range of the third folding plate is limited, so the angle of the cable tray elbow can be precisely adjusted. After the angle of the cable tray elbow is adjusted, the limiting block will be engaged in a third limiting groove on the connecting ring under the action of the return spring, thereby fixing the toothed ring in the current position.

[0014] As described above, a combined cable tray elbow includes a first cable tray and a second cable tray, which are connected by a hinge. It also includes: an adjustment mechanism located between the first and second cable trays, comprising a cable tray elbow, which includes a first folding plate, a second folding plate, and a third folding plate. The first folding plate is fixedly connected to one side of the first cable tray. The top outer walls of the first and second folding plates are respectively provided with a second limiting groove and a first limiting groove. The top inner walls of the second and third folding plates are respectively fixedly connected with a first limiting post and a second limiting post. The first and second limiting posts are slidably connected to the inner walls of the second and first limiting grooves, respectively. A limiting mechanism is located on the top outer wall of the first cable tray. The combined cable tray elbow provided by this invention has the technical effect of flexibly adjusting the angle of the cable tray elbow within a certain range, avoiding deformation or breakage at the elbow, which could lead to cable loosening or detachment, thus improving the stability and safety of the cable tray system.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0021] The present invention discloses a modular cable tray elbow, which is mainly used in scenarios where the connection method of traditional modular cable tray elbows may not be strong enough. During the installation process, if the size or angle of the elbow does not match the actual situation, secondary processing or adjustment is required. If external pressure is applied, the elbow may deform or break, which may lead to the cable loosening or falling off, affecting the stability and safety of the cable tray system.

[0022] Reference Figure 1 and Figure 4 A combined cable tray elbow includes a first cable tray 1 and a second cable tray 2, the first cable tray 1 and the second cable tray 2 being connected by a hinge, and further includes:

[0023] Adjustment mechanism: Located between the first bridge frame 1 and the second bridge frame 2, the adjustment mechanism includes a bridge frame elbow, which includes a first folding plate 3, a second folding plate 4 and a third folding plate 5. The first folding plate 3 is fixedly connected to one side of the first bridge frame 1. The top outer walls of the first folding plate 3 and the second folding plate 4 are respectively provided with a second limiting groove 7 and a first limiting groove 6. The top inner walls of the second folding plate 4 and the third folding plate 5 are respectively fixedly connected with a first limiting post 19 and a second limiting post 20. The first limiting post 19 and the second limiting post 20 are respectively slidably connected to the inner walls of the second limiting groove 7 and the first limiting groove 6.

[0024] Limiting mechanism: located on the top outer wall of the first bridge frame 1.

[0025] Among them, the first fold plate 3, the second fold plate 4 and the third fold plate 5 are all fan-shaped structures. The fan-shaped structure allows the first fold plate 3, the second fold plate 4 and the third fold plate 5 to bend naturally and adapt to different angles by adjusting the overlapping part of the fold. This design allows the cable tray bend to be more flexible when adjusting the angle and can easily adapt to various complex cable layouts and installation environments.

[0026] In the specific implementation process, the first folding plate 3 is fixedly connected to the first bridge frame 1, and the third folding plate 5 is fixedly connected to the second bridge frame 2. By fixing the first folding plate 3 to the first bridge frame 1 and the third folding plate 5 to the second bridge frame 2, the accidental movement or deformation of the bridge frame elbow can be avoided during use.

[0027] Specifically, during installation, the positions and angles of the first cable tray 1 and the second cable tray 2 are first determined. When the angle of the cable tray bend needs to be adjusted, the third folding plate 5 can be pushed, thereby causing the second limiting post 20 and the first limiting post 19 to slide within the first limiting groove 6 and the second limiting groove 7, respectively. This changes the folding angle position of the third folding plate 5 and the second folding plate 4. This design allows the cable tray bend to be adjusted within a certain range while maintaining the stability and integrity of the structure. The first folding plate 3, the second folding plate 4, and the third folding plate 5 can be rotated and adjusted to meet the cable layout requirements at different angles. After the cable tray bend is adjusted to the required angle, the position of the cable tray bend is fixed by the limiting mechanism to ensure its stability and safety, making it match the cable layout and preventing accidental movement or deformation during installation or use. This device can flexibly adjust the angle of the cable tray bend within a certain range, avoiding deformation or breakage at the bend, which may lead to cable loosening or falling off, thus improving the stability and safety of the cable tray system.

[0028] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, the top outer wall of the first bridge frame 1 is provided with a connecting assembly, which includes two fixing blocks 8. One fixing block 8 is installed on the top outer wall of the first bridge frame 1, and a support column 11 is provided between the two fixing blocks 8. One end of the first folding plate 3, the second folding plate 4 and the third folding plate 5 are all connected to the circumferential outer wall of the support column 11 by bearings. A stop block 12 is provided on the bottom outer wall of one of the fixing blocks 8.

[0029] One of the fixing blocks 8 has a mounting groove on its bottom outer wall and another of its top outer wall. The mounting groove is fan-shaped and the included angle between the inner walls on both sides of the mounting groove is 90 degrees. The mounting groove is fan-shaped and has a certain width, which allows one end of the first folding plate 3, the second folding plate 4 and the third folding plate 5 to have a certain range of movement in the mounting groove, and limits its maximum range of movement to improve the stability and reliability of the connection.

[0030] Specifically, one end of the first folding plate 3, the second folding plate 4, and the third folding plate 5 are all connected to the outer circumference of the support column 11 via bearings. This allows the cable tray elbow to rotate and adjust smoothly on the support column 11, thereby meeting the cable layout requirements at different angles. The use of bearings also reduces friction and wear, extending the service life of the cable tray elbow. The main function of the stop block 12 is to limit the rotation range of the cable tray elbow. When the cable tray elbow is adjusted to the required angle, the stop block 12 will prevent it from continuing to rotate, thereby ensuring the stability and safety of the cable tray elbow.

[0031] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the limiting mechanism includes a toothed ring 10, which is connected to the top outer wall of one of the fixing blocks 8 via a bearing. The top outer wall of the third folding plate 5 is provided with a toothed plate that meshes with the toothed ring 10. The top outer wall of one of the fixing blocks 8 is provided with a connecting post, one end of which is fixedly connected to a mounting plate 13. A connecting rod 14 is fixedly connected to the outer circumference of the mounting plate 13. A return spring 15 is wound around the outer circumference of the connecting rod 14. One end of the return spring 15 is provided with a limiting block 16. The top outer wall of the toothed ring 10 is provided with a connecting ring. The inner circumference of the connecting ring is provided with several equally spaced third limiting grooves 17 and connecting grooves 18. The depth of the connecting grooves 18 is less than the depth of the third limiting grooves 17.

[0032] It should be noted that the third limiting groove 17 is designed as a circular groove to ensure that the limiting block 16 can be stably inserted into it.

[0033] The limiting block 16 is a spherical structure, which is adapted to the third limiting groove 17. During the adjustment of the angle, the return spring 15 will maintain a certain tension, so that the limiting block 16 can slide along the inner circumference of the connecting ring under the action of the spherical structure. When the third folding plate 5 is rotated to the required position, the limiting block 16 will try to be inserted into the nearest third limiting groove 17 under the elastic force of the return spring 15.

[0034] Specifically, when it is necessary to adjust the angle of the cable tray bend, first manually compress and move the return spring 15 and the limiting block 16 towards the support column 11, and then manually rotate the third folding plate 5 to drive the toothed plate to move relative to the toothed ring 10. Since the teeth of the toothed plate and the toothed ring 10 mesh with each other, the rotation range of the third folding plate 5 is limited, so the angle of the cable tray bend can be precisely adjusted. After the angle of the cable tray bend is adjusted, the limiting block 16 will be engaged in a third limiting groove 17 on the connecting ring under the action of the return spring 15, thereby fixing the toothed ring 10 in the current position.

[0035] Working principle: During installation, the positions and angles of the first cable tray 1 and the second cable tray 2 are first determined. When the angle of the cable tray bend needs to be adjusted, the third folding plate 5 can be pushed, thereby causing the second limiting post 20 and the first limiting post 19 to slide in the first limiting groove 6 and the second limiting groove 7 respectively, thus changing the folding angle position of the third folding plate 5 and the second folding plate 4. This design allows the cable tray bend to be adjusted within a certain range while maintaining the stability and integrity of the structure. One end of the first folding plate 3, the second folding plate 4 and the third folding plate 5 are all connected to the outer circumference of the support post 11 through bearings. This connection method allows the cable tray bend to rotate and adjust smoothly on the support post 11, thereby meeting the cable layout requirements of different angles. After the cable tray bend is adjusted to the required angle, the position of the cable tray bend is fixed by the limiting mechanism to ensure its stability and safety, making it match the cable layout and preventing accidental movement or deformation during installation or use.

[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
